    I'm using a zBoost YX-520I cellphone signal booster and suddenly its power supply is blinking and does not power the device. In my experience, blinking power adapters indicate a short. The power adapter has a solid green when NOT connected to the device but as soon as it is connected to the device, it blinks. This can only mean that it's either shorted or its output current rating is reached (overcurrent). I tried using a 4.5V power supply and it powered up the device but I know that that is not good practice (I did that just to test). That simply means that the power supply of the device is broken.

    I'm having a hard time looking for a power adapter with output rating of 3.7V 2000mA. Can anyone help me on this? Oh and btw, how do I know if this adapter is linear or switching?

    Thanks for the help.
